What are the benefits of using PHP functions like http_build_query()?

When working with HTTP requests in PHP, it is common to need to build query strings to send data in a URL-encoded format. The http_build_query() function in PHP simplifies this process by taking an array of data and encoding it into a query string. This function automatically handles special characters and URL encoding, making it a convenient tool for constructing query strings for HTTP requests. 

$data = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'age' => 30
);

$queryString = http_build_query($data);

echo $queryString;
```

Output:
```
name=John+Doe&email=johndoe%40example.com&age=30
